<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>A widget will receive drag move events repeatedly while the drag is within its boundaries, if it accepts <a href="../qtwidgets/qwidget.html#acceptDrops-prop">drop events</a> and <a href="../qtwidgets/qwidget.html#dragEnterEvent">enter events</a>. The widget should examine the event to see what kind of <a href="qdropevent.html#mimeData">data</a> it provides, and call the <a href="qdragmoveevent.html#accept-1">accept</a>() function to accept the drop if appropriate.</p>
<p>The rectangle supplied by the <a href="qdragmoveevent.html#answerRect">answerRect</a>() function can be used to restrict drops to certain parts of the widget. For example, we can check whether the rectangle intersects with the geometry of a certain child widget and only call <a href="qdropevent.html#acceptProposedAction">acceptProposedAction()</a> if that is the case.</p>
<p>Note that this class inherits most of its functionality from <a href="qdropevent.html">QDropEvent</a>.</p>

<p>Creates a QDragMoveEvent of the required <i>type</i> indicating that the mouse is at position <i>pos</i> given within a widget.</p>
<p>The mouse and keyboard states are specified by <i>buttons</i> and <i>modifiers</i>, and the <i>actions</i> describe the types of drag and drop operation that are possible. The drag data is passed as MIME-encoded information in <i>data</i>.</p>
<p><b>Warning:</b> Do not attempt to create a QDragMoveEvent yourself. These objects rely on Qt's internal state.</p>

<p>The same as accept(), but also notifies that future moves will also be acceptable if they remain within the <i>rectangle</i> given on the widget. This can improve performance, but may also be ignored by the underlying system.</p>
<p>If the rectangle is empty, drag move events will be sent continuously. This is useful if the source is scrolling in a timer event.</p>
